I want to control each of the rotors directly in Offboard mode and thought I can do this using actuator_control topic. However, I am having difficulties in how to use this topic. My 2 main questions are:
- What values I have to use for “group mix” and “control” parameters
I think I have to use value 3 for the mixer group which is PX4_MIX_MANUAL_PASSTHROUGH, but I don’t know the parameters for “control” to control each actuators.
- The description of this topic says “Sends actuator commands to FCU”. Does this imply that I have to use additional Pixhawk connection to use this topic, unlike the usual setpoint topics?
